Temperature Measurements
WARNING: To avoid electric shock, disconnect test leads from any
source of voltage before making a temperature measurement. Be sure
that the thermocouple has been removed before changing to any other
measurement function.
1. Insert the type K thermocouple probe into the sub-miniature
temperature socket.
2. Turn the rotary switch to the
3. Read the temperature on the display.
Continuity Measurements
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive Ω jack. Observe
polarity.
2. Turn the rotary switch to the
3. Press the
4. Touch the test probes to the circuit or device under test. If the
resistance is less than approximately 30Ω the buzzer will sound
and the resistance appears on the display.
Diode Measurements
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive diode jack.
2. Turn the rotary switch to the
3. Press the
4. Touch the test probes to the diode under test. Forward voltage will
indicate 0.4V to 0.7V. Reverse voltage will indicate "OL". Shorted
devices will indicate near 0mV and an open device will indicate
"OL" in both polarities.
